Wind Power,Wind Turbine Manufacturer

Maglev wind power generators technology is the human magnetic levitation wind power technology and an excellent combination of technology, new energy development prospects of the most important path. This by the Shenzhen Shun Hei Electrical Technology Development Co., Ltd. invested construction testing ground for the inland Ⅱ wind source. Beaufort grading test using SX-CXF-based Zero Gravity products magnetic levitation small wind turbine at different wind speeds in the analysis of wind, current, voltage, transient and frequency to adapt to different types of wind performance data.

According to reports, the magnetic field of wind turbines manufacturers technology to break through the British physicist determined by the fetters of Enxiao Theorem is an important human use of wind energy breakthrough, zero-gravity magnetic levitation invented by the Chinese, not only to show the world’s advanced technology the forefront of scientific research strength, but also demonstrates the application of new energy future.

The dry season with the fan wind power generation, environmental protection and emission reduction, a strong wind to the power shortage will undoubtedly inject a needle “tonic” – wind Yakou as Kunming, the first wind farm wind power project approved by the eight months of construction, 22 wind turbines official “posts.” Currently, wind turbines countdown has entered the test run, then after the transfer of production, the estimated annual generating capacity of the Internet to reach 77,340,800 degrees.

Yesterday, the Evening News reporter walked into the location of wind farms wind Yakou, Fumin Xian Yongding street Xishan Xishan village pine house ridge and valley law united district offices around the neighborhood Fengbai mountain ridge. Reporters noted that the electric field north Fumin Xian, south of Xishan District, Kunming area away from the wealthy and the county and are relatively close, while the wealthy because the low-lying South High North, altitude difference large, mountainous Pingba less, climate typical low-latitude plateau monsoon climate, prevailing southwest winds year round, for the wind power turbines has created favorable conditions.

According to reports, the wind farm dynamic investment 387,642,800 yuan, put into operation, the estimated annual generation capacity of 77,340,800 online degrees, according to market price, the estimated annual economic benefits could reach 45 million yuan. Compared with the same scale thermal power plants, annual savings of about 22,400 tons of standard coal, the corresponding annual reduce emissions caused by burning coal, can effectively reduce sulfur dioxide, carbon monoxide, nitrogen oxides and soot and other emissions.

It is understood that wind Yakou wind farm project on April 15 this year, construction, to November 28, lifting 22 complete wind turbines … … at 22:50 on December 18th, enriching the final wind farm wind turbines manufacturers Yakou a unit grid. So far, wind farm wind Yakou 22 units have been completed dynamic debugging. Consumers short of work now in progress fan, to be entered eliminate lack of complete 250 hours trial run, then you can officially handed over the production, the electricity directly with the Yunnan Power Grid unified.

Reporters learned from a wealthy county, according to Fu Minxian the last stage of the construction of wind power planning, now the wind farm development and construction of wind farms with wind Yakou, Ma Ying Wind Farm, Rabbit wind farms, wind farm gold bronze basin. The four wind farms installed capacity of 153.5 MW total project is expected to fully completed during the second five.

Instead of using that system to arrive at a standard price, the government is considering allowing several big State-owned companies to plan such project through negotiating with local governments and authorities such as the State Oceanic Administration. Those initial plans would then have to receive the approval of the National Energy Administration before the work could begin.
“We hope this will become a more effective way to find a benchmark price for offshore windmill power projects,” said Shi Lishan, deputy director of the wind turbines administration’s renewable energy unit.
The practice of using auctions to set standard prices for offshore wind-power projects has evident shortcomings and was adopted merely as a provisional method at a time when few projects involving marine wind power were in operation for China, Shi said.
Last October, China completed its first public auction of four offshore wind-power generators concessions – deals in which a power-grid company agrees to buy a certain amount of power from a wind project for a certain price, thus protecting the investors in the project. The concessions were in Jiangsu province and were for a generation capacity of 1,000 megawatts.
Four State-owned companies, including China Datang Corp Renewable Power Co and China Longyuan Power Group Corp Ltd, were the winners at the auction.

Seeing huge rotor blades slash the sky in Germany has become commonplace over the last 20 years, as wind turbines have multiplied across the countryside.

But as the country races to meet European Union renewable energy targets, companies are not only under pressure to meet the time constraints of the EU’s Energy Roadmap 2050 – which highlights wind energy as a prominent future power source – they are also running out of room to expand on German soil.

Meanwhile, the US is pursuing its own renewable energy goals – a US Department of Energy report published in 2008 suggests cover 20 percent of American power needs with wind energy by 2030. And German experience in the wind energy sector will be an important component for the United States, according to Michael Blank, vice-president of the German-American chamber of commerce.

“I think what’s good for Europe is also good for the US,” Blank said.

The United States is also good for Germany small wind turbines industry in terms of potential wind power far outstripping those of Europe.

The construction of wind farms at sea are also disadvantages. The establishment of wind turbines in the sea base and the high price of the laying of submarine cables, and high maintenance costs, resulting in offshore wind farm construction and operation costs than onshore wind farm high. Therefore, most of the offshore wind farm by private companies or public agencies have, instead of taking co-ownership structure of the way operations.

Kroger said that in order to reduce the cost of offshore wind farms to achieve economies of scale, the best way is to build more than one operating wind turbines generator continuous operation. To this end, Dong Energy on the west coast of Jutland in Denmark built a large installed capacity of 160MW offshore wind farm. There is also a very large installed capacity of 400MW offshore wind farm under construction, the wind farm will have 111 wind turbines that can supply 40 million Danish households.

On land to build such a large wind farm is almost impossible, so offshore wind farm has a unique scale advantages. By the overall planning and operation of large-scale, offshore wind farm costs can be reduced to the same level with the onshore wind farm.

Reasonable price to support the development of wind power industry

Currently, about 17% of Denmark’s energy from windmill generator , biomass and solar energy and other new energy sources. Government plans, by 2020, wind power will account for 50% of the total electricity generation; 2050, will completely get rid of dependence on fossil fuels. To maintain the sustainable development of wind power industry, the need for green energy to develop a reasonable pricing policy.
To support sustainable energy projects, the Danish government to pay the price of wind power generators is slightly higher than the market price. Ka Yueer that high prices will not only improve the overall energy prices, and the wind will bring a bad impression that wind energy is good but the high prices.

In this regard, Gardner said: “We must consider not only economic benefits, but also to consider the environmental and social benefits. With the business philosophy of innovation and technology, wind power will be increasingly competitive, we used to support wind power development capital and investment will be less and less. “

With a large number of wind energy resources in the District and the unique advantages, in recent years, Denmark, to develop windmill  power and related industries, with remarkable results. At present, there have been hundreds of building onshore wind farms and several large offshore wind farm. According to the Danish Energy Agency data show that in 2010 the total installed capacity of wind turbines in Denmark has reached 3800MW, accounting for 25% of the total generating capacity. Among them, the offshore wind farm of 423MW installed capacity increased from 2008 to 2010 of 868MW.

Wind power cooperative ownership structure of industry

Danish wind farm is unique in its ownership structure of the collectivization, ordinary residents can join the government-backed wind power projects, wind farms to become shareholders. By way of holding the residents, a good solution to the local residents due to wind damage to the landscape, noise and other adverse factors arising from the resistance.

Copenhagen Business School professor  that the cooperative form of ownership is a long tradition in Denmark, Danish banks, such as slaughterhouses and dairies have a wealth of operational experience, onshore wind farm in the 1970s also began to use this form of operation. For those who have backyard wind turbines residents, the windmill generator turning at the same time, a steady stream of money flowing into their bank accounts.

Middelgrunden is Denmark’s first cooperative ownership structure approach to offshore wind farm operation, located in Copenhagen, East Coast, formed by the 20 windmills on the Taiwan Strait. The board members Hans Christian Anselunsen that Denmark uses cooperative ownership structure model, is to make wind power more people to participate in the plan.

Cooperation with Middelgrunden ownership structure of the wind farm idea proposed in 1993, after local residents and non-governmental organizations reached after consultation. Selun Sen said: “You pay 4250 DKK (Danish Krone $ 1 co-5.5) to buy a share, and then return 600 Danish kroner per year, which means that the initial return rate of 14% to 15% rate of return after slightly lower, but after 10 wind turbine generator years of recoverable costs, but also get 7% annual rate of return. people are very satisfied with this result, because the money in the bank than the higher income also contributed to environmental protection . “

2020 stand-alone wind turbine power will reach 20 MW. This conclusion comes from wind power generators projects in Europe Upwind feasibility study report.

A country with 200 m rotor diameter, 20-megawatt electrical power of giant wind turbines will be put into use in 2020. According to Upwind wind energy project feasibility study report, significant technological innovations and design development will be necessary.

Expansion fan will be an important expansion of the European wind energy opportunities, particularly through the construction of offshore wind farms, making it possible to achieve, by 2030 wind power to provide electricity for Europe 26-34% electricity target.

As significant technological advances and design changes, the Netherlands Energy Research Centre of Jose Boyle Siken Si said: “To build 20MW of fans, not just the current 5MW turbine upgrades simple, but we have determine the design, materials and innovation necessary to operate the fan. ”

For example, the leaves will reach 200 meters in diameter, and will be more lightweight and flexible. In addition, the leaves also equipped with sensors to achieve real-time transmission, and thus make better use of wind energy, and can check the blade tension.

Of course, this R & D expenditures but also to overcome the problem, the European Wind Energy Association CEO Christian said: “If the EU does not make a clear home wind generator commitment to the research and development, then the 20MW turbine will eventually vanish into thin air.”
